Exercise 21.39 A point charge is at the origin. With this point charge as the source point, what is the unit vector in the direction of (a) the field point at x = 0, y = -1.35m; (b) the field point at 2 = 12.0cm, y = 12.0cm; (c) the field point at x = - 1.10m, y = 2.60m? Express your results in terms of the unit vectors i and ſ.
